Action Instruments Q403 DC Input Multi-channel Isolator

DC Input Multi-channel Isolator

The ActionI/Q model Q403 is a fast response, DIN rail mount, DC input signal conditioner, with 2000VAC isolation between input output and power. Available as a single channel signal conditioner (1 input /1 output) or as an optional multi-channel signal conditioner (2 inputs/2 outputs, or 1 input / 2 outputs), the Q403 maintains the high 2000VAC isolation from channel to channel, as well as input to output to power. Factory configured input and output ranges support bipolar voltage signals or unipolar ranges of 4-20mA, 0-5V, 0-10V and 1-5V. Front accessed zero and span potentiometers allow adjustment of offset and gain to compensate for sensor errors or signal losses.

All ActionI/Q modules feature SnapLoc, plug-in, screw terminals for easy installation and low Mean-Time-To-Repair (MTTR). If desired, two or more modules can slide together and interlock for solid, high density mounting. This is accomplished by removing either the DIN rail foot or the adjacent unit’s face plate, for right side or left side mounting, respectively. The module to be attached will easily slide on to the side of the mounted unit.
